In case of hydraulic components, the dimensions are often crucial for the proper functioning of the component. At Galvano Hengelo it is possible to provide dimensionally critical parts with a partial zinc-nickel layer. This way, the component is only partially coated with zinc-nickel. This prevents screw-in components such as cartridges or end plugs from no longer fitting due to tolerance problems after surface treatment.
Choosing partial treatment with zinc-nickel prevents parts from having a lower friction coefficient than the original metal. This can have major consequences, such as, in case of hydraulic pulsations, possible loosening.
With a partial zinc-nickel treatment, we offer corrosion protection of at least 1,000 hours NSS, without fitting problems. The perfect solution for your hydraulic screw-in components!
